Coupler bolt termination system
View Patent ↗A termination system which attaches a conventional threaded rod or bolt to a cable. An anchor is attached to an end of a cable using known techniques—such as potting. A threaded rod or bolt is placed on the anchor, pointing away from the direction of the cable. The rod or bolt is mechanically attached to the anchor using several different techniques. The result is an anchor assembly including a threaded protruding shaft. Because the assembly uses an inexpensive prior art rod or bolt, the machining operations are confined to small components needing relatively little material removal.
1. A termination system for an end of a cable, comprising:
a. an anchor, attached to said cable, wherein said anchor has a first end proximate said end of said cable and a second end proximate said cable but distal to said end of said cable;
b. a coupler, including,
i. a first side proximate said anchor,
ii. a second side distal to said anchor,
iii. an internal cavity,
iv. a hole passing from said internal cavity out said second side;
c. said coupler being attached to said anchor with said internal cavity of said coupler lying adjacent to said first end of said anchor;
d. a bolt having a bolt head with six hexagonal flats, and a threaded shaft, wherein a portion of said threaded shaft passes through said hole in said coupler and extends beyond said coupler and away from said anchor, and said bolt head lies within said internal cavity in said coupler;
e. said hole in said coupler being too small to allow said bolt head to pass; and
e. wherein said coupler includes at least one wall in said internal cavity positioned to bear against one of said hexagonal flats on said bolt head, thereby preventing said bolt from rotating with respect to said coupler.
2. A termination as recited in claim 1 , wherein said attachment between said coupler and said anchor comprises a threaded connection.
3. A termination as recited in claim 2 , further comprising a spacer placed between said bolt head and said anchor.
4. A termination as recited in claim 1 , wherein said at least one wall in said internal cavity forms part of a pocket sized to receive said bolt head.
5. A termination as recited in claim 1 , wherein said anchor is attached to said cable by potting.
